Looks like it is configured accoridng to this:

Could be an IRQ conflict as was suggested in another post.
I thought the configuration files were done in a way that cards using
snd_bt87x would not become card 0 if the module was loaded before the
module for the sound card, but if you ran alsa conf that may not be the
case.
First, from the command line I would type:
alsaconf
: to reconfigure alsa making sure that VIA gets indexed as card 0,
then if the problem persists I would do:
cat /proc/interupts
: to see if an IRQ is being shared between the audio device and the TV
card. If the IRQ is shared then try moving the TV card to another slot.
Could be the VIA chipset and the TV card just don't like each other as
well. I have an older Pinnacle card on a VIA chipset board and mostly it
works, but once in a while the system will get a little tempramental
and reboot or lock up when I open TV Time or switch desktops while TV
Time is open. Sound was never an issue for me though. It's actually
been tempramental on 2 other VIA chipset boards as well, but the system
it's in now is the first one with on board audio and the other two
systems would only lock up some times when switching desktops.
Later, Seeker
